If the terminal speed of a sphere of gold (density =19.5 ~kg / m ^3 ) is 0.2 ~m / s in a viscous liquid (density =1.5 ~kg / m ^3 ) of the same size in the same liquid.

Options

  1. A0.2 ~m / s
  2. B0.4 ~m / s
  3. C0.133 ~m / s
  4. D0.1 ~m / s

Correct answer

D. 0.1 ~m / s

Step-by-step solution

v _ s v _ g = ( _ s - _ ) ( _ g - _ ) v _ s =0.1 ~m / s
